Embodiment

[0120] This example combines the data collected by the geomagnetic coil detector and the phase data of the signal controller at the three intersections of Science Avenue in Shushan District, Hefei City, Anhui Province, respectively, where Tianda Road, Huangshan Road, and Tianhu Road intersect. , the present invention is carried out concretely. In the example, the position of the intersection is shown as figure 2 shown.

[0121] The online evaluation method and system for traffic signal controller control effect proposed by the present invention mainly include: collection of intersection traffic data, storage of intersection traffic data, extraction and processing of traffic data, evaluation of traffic signal controller control effect, evaluation data storage, traffic signal optimization in six steps. In the implementation of the example, it specifically includes five steps in addition to the optimization of traffic signals:

[0122] Step 1, collection of intersection traff...

Abstract

The invention discloses an online evaluation method and system for the control effect of a traffic signal controller. Real-time traffic flow data collection is carried out through a detector arranged at a signal intersection, and the traffic signal controller collects signal light data in real time, and the collected The data is uploaded to the road detector database and the traffic signal controller database on the server side; the collected data is extracted and processed in real time on the server side, and the basic traffic parameters are calculated, and the software calculates the evaluation index of the traffic signal controller control effect accordingly. And store the results in the control effect evaluation database to complete the online evaluation. According to the evaluation data, traffic signal optimization can be carried out, and the optimization information can be fed back to the traffic signal controller to realize dynamic traffic signal control.

Description

technical field [0001] The invention relates to the field of road traffic signal control, in particular to an online evaluation method and system for the control effect of a traffic signal controller. Background technique [0002] Traffic signal controllers at road intersections can effectively guide traffic flow by allocating road rights in time and space, so as to ensure the safety and smooth operation of intersections. The control effect of the traffic signal controller is not only related to the operation efficiency of an intersection, but even affects the road traffic operation status in the entire urban area, resulting in regional congestion. In addition, the traffic volume has the characteristics of uneven time distribution, especially in peak and off-peak, day and night, weekdays and holidays, and other time periods. Therefore, timely and correct evaluation of the control effect of a traffic signal controller is conducive to making timely adjustments to improve the ...
